The fire was finally brought under control at about 5:30 a.m., after causing an estimated $250,000 in damage, he said. The only injury reported was to a fireman, after debris from the blaze landed in his open eyes.

Once the fire was out, staff from the city’s Public Works Department arrived with a backhoe and several 30-cubic-yard trash containers to begin removing debris from the house. They were still there Wednesday afternoon, he said.

Neighbors had repeatedly complained about the accumulation of material inside and outside the home, and Assistant City Manager Jim Hynes e-mailed neighbors early Wednesday afternoon to report that “staff from Health and Human Services, Environmental Health, Building and Safety, Fire and Police have all tried on multiple occasions to assist the homeowners to address the health and safety issues ... but without the permission of the homeowners, we were never able to enter the home.”

The city had won a court-issued nuisance-abatement order that allowed municipal workers to remove debris from the exterior side and back yards, he reported.

“We are saddened by what happened in your neighborhood, and once we get a report from BFD, we will do a careful review to see what, if anything, could have been done differently,” he wrote.

Deputy Chief Dong said the cause of the blaze remains to be determined..
